Subject: Stonefield SWM Amendment and Final Site Plan Amendment
Max,
You had asked for a description of what the changes were for the amendments that we have submitted.
Both the SWM amendment and the Final Site Plan Amendment have been submitted to allow for the utility and
stormwater infrastructure to be installed for the Costco building and allow for the design and construction of the "G"
block in Stonefield. The building locations have shifted since we first laid out the current approved plans.
For the SWM Amendment:
The Vorthechs and Stormfilter units were relocated approximately 140 feet East towards Rt. 29. The relocation of these
devices required the addition of manhole 167.1 in order to maintain a distance of less than 300 feet between manholes.
Manhole 176 on the pipe run that collects the runoff from the North Sperry Interceptor was relocated approximately 90
feet North and 120 feet East. The point of connection for the North Sperry Interceptor was relocated to MH 169.
Additionally MH 181 that collects the drainage from RT. 29 has been reconfigured to tie into the pipes discharging from
the North UGD. The revisions to the North Sperry Interceptor and the pipes from Rt. 29 allow for one connection point
to the existing 42" pipe under Rt. 29 rather than the three points of connection proposed on the previous amendment.
For the Final Site Plan Amendment:
The water and sewer lines were adjusted to go around a proposed building that will be constructed on the north east
corner of block"G".
In addition we relocated the parking in block"G" so that it would be installed where the Vortechs and Stormfilter will be
installed.
If you have any questions please give me a call.
Thanks,
